TO ALI; WHOM IT MAY CONCERN:

. Be it known that I, ANTOINE ST. LOUIS, of Keeseville, in the county of Clinton, and in the State of New York, have invented certain new and useful Improvements in Machine for Making Horse-Shoe Nails; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

In the annexed drawings, making part of this specification, A represents the frame of the machine, which is made rectangular in form, is built in a very firm and substantial manner, and is supported upon suitable legs. Erected upon the two sides of this frame are the uprights B B and C C. The uprights C C are connected at their upper ends by a cross-beam, D, which is framed into them. L represents an eccentric shaft, which lies beneath the frame A, and crosswise of it, having its bearings in suitable supports, which project from the under side of the side pieces of the frame. This shaft has a crank-handle or a drum upon one end of it, by means of which motion is communicated to the machine, and on the other end it has a gear-wheel, T, seen in red lines, Figure 1. This gear-wheel T meshes into a larger gear-wheel, R. The wheel R revolves upon its own short shaft, which is secured to the side of the frame, and is provided upon its inner face with a projection, '26, for

operating a device for cutting oil the nail, as will be hereinafter described. K represents a pitman, which is V provided with a collar at its lower end, which said collar fits over the eccentric portion of the shaft L. The upper end of this pitman is pivoted between two bars E. The bars E are firmly secured at one end to a shaft,

M, which lies crosswise of the frame A, and has its bearings in the uprights B B. This shaftMpartially rotates backward and forward, when the machine is in motion, giving an up-and-down motion to the outer ends of the bars E. E represents one of the hammers of the machine, which is firmly secured to the bars E by means of suitable bolts. F represents a hammer, which has a shaft passing through its centre, said shaft lying-crosswise ofthe frame, and having its bearings in the front legs of the frame. The rear end of this hammer is connected to the bars E by means of the connecting-rod or shaft G. It will'now be seen that when the shaft L is rotated its pitman K causes the bars E to communicatemotion to the hammers E and F, so thattheirouter ends, which are provided with the adjustable faces a a, approach and recede'from each other with perfect precision at each revolution. H H represent the two side hammers, which have trunnions on their upper and lower sides, at their rear ends, and these trunnions have bearings in a cross-piece of the frame, and in the cross-beam D. These ham mers Hhave arms n projecting from them horizontally near their rear ends, and to these arms is pivoted one end of the connecting-rods J. The rods J have their rear ends pivoted'to arms m, which project from the under side of the shaft M. When the shaft M partially rotates backward and forward, the rods J J communicate motion to the hammers H H, causing their ends, with the faces a a, to approach and recede from each other with per feet uniformity. 'The faced ends of the hammers are slightly bevellad to suit the shape of a horse-shoe nail, and are so arranged that the vertical hammers strike the nail on its under and upper side, both at the same instant, and the lateral hammers strike it simultaneously with each other on its sides.

The bar of iron of which the nail is made is held in the guide box e, so that it is suitably presented to. the hammers. This box is secured to a metallic spring-bar, 0i, which'said bar is secured to an arm, z, of an adjustable cross-piece, N. The cross-piece N is suspended between the guides P P, which project from the under sides of the frame-piece A. 0 represents a lever, the upper end'of which is pivoted to the frame-piece A,-

said lever being provided near its centre with a longitudinal slot, through which it is secured by a headed pin to the cross-piece N. The object-of this lever is to give an endwise movement to the piece N when desirable. S represents the knife of the machine for cutting oil the nail when finished. This knife is pivoted at one end to a portion of the frame, while its other end plays up and down, and cuts the nail between its own edge and the edge of a stationary blade, which is secured on the inner side of the frame-piece Pivoted to the knife S is -a slotted bar, Q, and a pin, X, passing'through the cross piece N, and through the slotfof the bar Q, confines said bar to the cross-piece. A spring, 9, bears the knife upward, and a spring, 20, bears the arm .2 upward, and a spring, 11, returns the cross-piece, after it has been moved endwise to its normal condition or position, which is the one represented in Figure 2. When a nail has been finished and is to be cut off, the operator, by

means of lever 0, gives the cross-piece N an endwise movementtoivard the wheel R, until the projection u, before spoken of, strikes the arm N of the erossepiece N; This end of the cross-piece being borne down by the projection u, the arm z draws the box a, with its nail-bar, down into a slot or opening seen in the frame-pieee A,

so that the nail rests under the knife S. Just as the nail is placed under the knife the pin 1, on cross-piece N,

strikes the bottom of slotfin bar Q, and, drawing said bar down, the knife is forced by this bar upon the nail so as to sever it from the nail-bar. When the knife has descended its proper distance, and the nail is severed, the projection 14 passes the arm N, and the cross-piece N and knife S are returned to their normal position by means of their respective springs, as has been described. It will be readily perceived that the nail is cut off as often as the operator may desire, or whenever it is finished. The faces a a and a a of the hammers are made movable, so that they can be renewed or changed if desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. Constructing, arranging, and operating the hammers E F and H H in the manner and by the means herein described, whereby said hammers are given a precise stroke, and one which draws the nail, substantially as represented. I

2. The combination of the cross-piece N, the pivoted arm :2, box e, knife S, bar Q, and wheel R, with its projection, used substantially as and for the purpose set forth.

In testimony thatI claim the foregoing I have hereunto set my hand this 30th day of July, 1867.
